Play our QR Code scavenger hunt at the Faire

Thom Nichols is building a mobile QR Code scavenger hunt for the RI Mini Maker Faire based on QuiRk: A Cross-Platform QR Scavenger Hunt Game, which he launched at this year's Wooly Fair. We'll be hiding QR Codes all over the RI Mini Maker Faire. If you find them all, you'll be entered in a (free) drawing to win one of three awesome prizes, which we'll be announcing soon.

In this video, you can see my MakerBot Thing-O-Matic printing out a raised-relief 3D rendition of a QR Code using polymaker's qr2cad utility. The QR Code is still fundamentally 2D, so I printed the background and first layer using a natural/clear PLA, then switched to a blue PLA for the QR Code version of it.

The 3D-printed QR Codes will link to the start page for the game (it's web based so it works with any mobile phone that can scan a QR Code), but the QR Codes you'll be hunting for will be much smaller than this one.
